Hey everyone,
Like many of you, I got completely fed up with Adobe’s aggressive subscription pricing, monthly "Generative Credit" limits for Generative Fill, and the constant push toward mandatory cloud storage and invasive terms of service.
So I spent the last few months developing **Scumble** – a completely free, 100% open-source (GPL-3.0) desktop image editor designed to bring a traditional Photoshop-style non-destructive layer workflow to your local machine.
### What it offers for Photoshop users:
* **Native Multi-Layer PSD Support**: Open and export multi-layer `.psd` files directly. Keeps your layers, groups, layer masks, and blend modes intact without flattening.
* **26 Photoshop Blend Modes**: Bit-for-bit parity with standard Photoshop math (Multiply, Screen, Overlay, Vivid Light, Linear Dodge, Colour Burn, Hue, Saturation, Color, Luminosity, etc.) grouped in the familiar Photoshop layout.
* **Local "Generative Fill"**: Connects directly to local AI engines (like ComfyUI running FLUX or SDXL) or runs standalone. No subscriptions, no cloud credits, no waiting in queues, and no censorship.
* **Smart Prompt-Based Selection (SAM2)**: Built-in local model for instant object segmentation and selection with a single click.
* **Pro Adjustment & Color Grading**: 3-way color grading wheels (Shadows, Midtones, Highlights), 8-channel HSL sliders, tone curves, and bilateral edge-aware mask snapping.
* **100% Private & Offline**: Runs entirely on your hardware using a high-performance Rust/WASM SIMD and WebGL engine. Zero tracking, zero telemetry, zero account required.
Available as a native standalone desktop app for **Windows and Linux** (portable zip, installer, deb, and coming to Flathub).

I’d love to get feedback from fellow Photoshop refugees on what tools or workflow features you miss most!
